Other core components on the applications circuit board include the motion sensor/accelerometer that enables the iPhone's whiz-bang ability to auto-rotate the display's orientation (A), the 24-bit RGB display interface from National (B), and Wolfson Microelectronics' audio codec (C). In the upper left, you can see the iPhone's camera. The Apple-branded processor (D) is one of the largest components here: The 620-MHz ARM1176JZF application processor has 1Gb of DDR SDRAM memory from Samsung. (iSuppli has narrowed down the processor's source as being either Samsung or Marvell).
